That's considerably less in-depth than the criticism itself. The post you linked is mainly complaining about how mean some people were to Schildt and brushes aside the criticism on the basis that Schildt had good intentions. You'll notice that he tries to link the widespread criticism of Schildt's books (I mean, it's in the "learn C" newsgroup FAQ) with some anonymous trolls' death threats against blogger Kathy Sierra. It's basically the "LEAVE BRITNEY ALONE!" of the programming world.

I also think that post's phrasing has confused you. When he says "teaching C in practice," he doesn't mean teaching C-isms in a C++ book — he means C as it is (incorrectly) used in practice, such as teaching implementation-dependent assumptions and pretending that they're part of the standard, as well as simply wrong code that might appear to work right "in practice" in certain situations. For example, his "Annotated ANSI C Standard" stated that void main(void) was a valid main function and that padding only appears at the end of structs.
